Comparison of special judo fitness test and dynamic and isometric judo chin-up tests’ performance and classificatory tables’ development for cadet and junior athletes

Abstract

The aims of this work were to compare the performances of male and female cadet and junior judo athletes and to develop classificatory tables to these judo-specific tests for international-level from these ages. Data collected during training camps of male and female cadet and junior judo teams from three nations (Brazil, Serbia, and Spain) were analyzed, totalizing 252 individual results of special judo fitness test (SJFT), and 222 and 208 of dynamic and isometric judogi chin-up tests, respectively. Juniors performed better than cadets in the SJFT, with higher number of throws in A, B, C, and total (P<0.001 for all comparisons), lower final heart rate (P=0.021), and lower index (P<0.001), as well as higher relative performance in the dynamic chin-up test (P<0.001). Furthermore, male athletes presented better performance compared to female athletes in the SJFT (higher number of throws in A, B and total, and lower index) and in the isometric and dynamic chin-up tests (higher absolute and relative performances) (P<0.001 for all comparisons). Considering these differences, tables were established by sex and age groups, using percentile values. Thereby, each of the parameters of the SJFT (number of throws, heart rate after and 1 min after the test, and SJFT index), as well as absolute and relative results in chin-up judogi tests, were classified by sex and age. These classificatory tables can be useful for judo coaches to monitor specific physical performance during different phases of periodization process.

Maximal isometric handgrip strength: comparison between weight categories and classificatory table for adult judo athletes

“…These values can be used as a reference to guide judo athletes’ physical training and can be relevant for goal setting concerning maximal strength performance either peaking for a specific competition or during different phases of the rehabilitation process. The response to different periodization training programs can also be monitored using this table as a reference, as proposed for other tests (Agostinho et al, 2018; Branco et al, 2017; Branco et al, 2018). Future studies should focus on table development for female judo athletes and to athletes from different age categories.…”

“…Pearson correlation coefficient was calculated to determine the relationship between variables and classified according to Hopkins (2018). To develop a classificatory table for each maximal isometric handgrip strength variables, percentile values were adopted to establish the following categories, as used in previous publications with judo athletes (Agostinho et al, 2018; Sterkowicz-Przybycień and Fukuda, 2014): excellent, highest 5%; good, next 15%; regular, middle 60%; poor, next lowest 15%; very poor, lowest 5%.…”

“…Given the relevance of grip dispute in judo, classificatory tables were developed for both isometric strength-endurance and maximal strength (Agostinho et al, 2018; Branco et al, 2017; Branco et al, 2018). Strength-endurance classificatory tables were developed for adult male (Branco et al, 2017), cadet and junior male and female judo athletes (Agostinho et al, 2018), using a chin-up test gripping the judogi. However, only one study proposed a classificatory table for maximal isometric handgrip in adult judo athletes (Branco et al, 2018), but reported only the absolute and relative value for the sum of the two hands.…”

CrossFit Training Impact on the Level of Special Physical Fitness of Young Athletes Practicing Judo

“…of junior foreign athletes (Agostinho, Olivio Junior, Stankovic, Escobar-Molina, & Franchini, 2018), but the differences are insignificant. Interestingly, the SJFT index indicators of young (16-17 years old) athletes compared with SJFT data of Russian older athletes (19-23 years old) (Osipov, Kudryavtsev, Iermakov, & Jagiello, 2018) turned out to be higher.…”

Contest coefficients of the elite judo athletes of Russia and Kyrgyzstan (less than 60 kg, 66 kg, 73 kg and 81 kg) from 2010 till 2015

“…Today, unfortunately, the experts have not come to a common opinion about the advantage of applying a certain rating or information technology in the process of training the elite judoka [30]. Various authors suggest using different technologies and methods for assessing the level of the athletes' preparedness [31,32]. A large set of different data and criteria indicates the need for further scientific research in this direction.…”
